'ToaZZwMmitmag/comem:

Be it'known that I, Gnome J. HUNTIJJY, a British subect, residing at Baltimore, in the State of aryland, have invented Eertain new and useful Improvements in Packaging Apparatus, fully described Aand represented in the following specification ,and the accompanying'drawings, forming a part of the same. f l This .invention relates to packaging apparatus and particularly to that t'fp'e 4of packagin apparatus known as so a inachines. uch machines ordinarily serve to fill bottles or 'similar receptacles with a charge of syrup or the like anda charge of l carbonated water andto apply aclosure to the filled bottle.

Soda machines as heretofore known have been subject to certain disadvantages. For

p example, their operation has been 'attended with a loss of as through snifting and a loss of syrup t rough foamn Further, the control of the quantity o liquid delivered has been uncertain as the quantity has depended on some such element as the rate of speed of o eration, or 'the size of v the bottle presente Also there has been more or less loss of bottles by breakage due to an excessive gas'pressure for a given degree of carbonation. 4

It is the principal object of the present invention to provide a packaging apparatus of the type'inentioned that reduces the loss of gas and syrup to a minimum; that de- 35 livers uniform measured quantities of liquid regardless. of the rate of speed of operation or the size of bottle presented; that makes possible the packaging of a highly carbonated product with little loss-by breakage and that is ca able of high speed o eration. With 't is general ob'ect an other objects and advanta es, whic will be obvious to those skilled 1n the. art, lin view, the invention consists in the features, vdetails of construction, arrangements of parts and combinations which will first be described in connection with the accompanying drawings. and then more particularly pointed cut.

a complementa Referring en the drawings, the; machine p illustrated as an exam le is supported by a standard 101 to whic is secured a housing 102 .which provides bearings 103 for a power shaft 104. Power is derived in any suitable manner, as, for example, b

a belt 105 running over a pulley 106 whic carries a clutch member (not shown) of the expanding ringJ type. Cooperating with the clutch mem er carried by the pulley is clutch member 107 which is slidably key to the power shaft 104 and is operated by a yoke 109 and control handle 110. -The construction here shown is arranged to be operated at'different speeds. To this end, on the power shaft is slidably keyed a gang gear 111 which, in the present instance, comprises three pinions. Eachl of these pinions is designed to mesh with a complementary pinion on ,the gang gear 112 on the shaft 113. The gang gear 111 is shifted to vary the speed of the machine by means of a lever 114, shaft 115 and block 116 (Figs 17 and 18) which engage a yoke 117 slidable on a shaft 118. To properly locate the gear shifting apparatus, this shaft 118 has a plurality of circumferential grooves 119 arranged to en age a spring pressed dog 120, carried by t e yoke. The dog 120 also serves to prevent creeping of the gang gear. To facilitate gear changing and for setting the machine the drive shaft 104 carries at its outer end a hand wheel 121. On the shaft 113 isa bevel pinion 122 meshing with a similar gear 123 keyed to a vertical drive shaft 124 by keys 125, ythis connection being arranged to permit the vertical drive shaft 124 to slide with respect to the bevel gear 123 when the position of the apparatus is adjusted for bottles of different size, as hereafter described.

There is provided a packaging head and a bottle support capable of relative movement to assemble head and bottle in filling relation and capping relation. In the apparatus illustrated asian example the bottles are filled andcapped by a relatively stationary ackaging head 200 carried by a frame or ousing 129, the bottles, fed across a relativel stationarytable onto an elevating table, belng elevated to and withdrawn from this head. In order that the machine may be adapted to bottles of different size. i. e., quarts, pints, and the like, the filling and ,bodily movable with respect to e cap ing head with itsaoci'ated i! P relatively vstationary parts. As here shown,

Vsliding in the tubular portion. 130 of the -base 101 is a column 131 to which the housing 129 is secured. This column is bolted or otherwise attached to a rod 132, threaded through a nut 133 having, on its periphery teeth meshing with a worm 134 which is rotated by a handle 135. Operation of this handle raises or lowers the rod 132, thereby raising or -lowering the column 131 and housing 129, which carries the fillingand capping head. The colunm is locked in its adjusted positionby means of a clamping bolt 136 and rotation of the column is pi'evented by a pin 137 riding .in a suitable groove formed in the column.

The apparatus here illustrated as an example comprises what may be designated as six major mechanisms; the bottle feed, the bottle elevating mechanism, the gasket sealing mechanism, the nozzle moving mechanism, the water pump and the syrup pump. These, in the present embodiment, are divided into two groups, the bottle feed and bottle elevating mechanism forming one group which is carried by the base, t-he other four forming the second group which is carried by the adjustable frame or housing 129. The bottle feeding and elevating mechanisms are actuated by camsV forming what may be termed a lower cam group. This group comprises a bottle elevating cam 142, a worm wheel 143 and a bottle feeding cam 144, these three parts being bolted or otherwise secured together as a unit, and rotatable on a stationary shaft 145. Meshing with the worm wheel 143 is a worm 146 formed on or secured to. shaft 147 which is driven through a suitable connection, by the bevel gear 123. As here shown, in order that proper alignment may be made, this connection comprises the Oldham couplin 148, 149, 150, the lowest member 149 of t is' coupling being secured to shaft 147, and the upper member 150 bein keyed to a sleeve 151 formed as part of the bevel gear 123. With this construction the drive above described rotates the bottle elevating cam and the bottle feed cam.

Means is provided for feeding bottles one after another to a position beneath the filling and capping head by a step by step movement. In the embodiment illustrated, the bottles are supported o-n a stationary table 155 carried by a bracket 156 and are moved into position by a bottle dial 157. This dial has a plurality of spaced sockets adapted to' receive bottle-embracing bushings 158 which are interchangeable, the bushing used being adapted for the particular size and shape of bottle being filled. The dial 157 is secured to a vertical shaft 159 having bearin in the table 155 and bracket 156., Secure to this i tabacs# shaft 159 is a ratchet wheel 160 having a lurality of spaced notches 154 adapted to lie engaged by a drive pawl 161. This drive pawl is reciprocated by a rocker lever 162 and is heldV to its duty by a spring 163. The

rocker lever is ,connected by means of connecting rod 164 with a lever 166 -p1voted on a stud 167 and carryin at its other end a camroller 168 which ri es on the bottlel feed cam 144. The roller is held to the cam by means of a spring 169. As the bottle feed cam rotates, the pawl is operated to drive the ratchet forward with 4.a step by step movement, thus giving a similar movement to the bottle dial.

ThereA is provided means for locking the bottle feed mechanism `against movement in either direction, and in constructions embodying the invention to the best advantage, this is accomplished by locking the ratchet between its successive feeding movements. Although capable of various constructions,

in the present embodiment, the ratchet is at all times locked a ainst backward movement by a pawl 170 pivoted to a stud 171 and yieldingly held against the ratchet by a spring pressed pin 172. The ratchet is locked against forward movement between its bottle feeding movements by a similar pawl 173 pivoted `on a stud 174 and held' against the ratchet by a spring pressed pin Means is provided for releasing locking pawl 173 at the proper time to permit the drive awl to advance the ratchet on its bottle feelding stroke. As here shown, the rocker lever 162 carries a wiper 176 which, as the drive pawl makes its backward stroke, lifts the locking pawl out of engagement with the ratchet notch. As a result, on the forward stroke of the drive pawl the ratchet is free to be moved forward one stroke, whereupon the locking pawl drops into the next notch. As will be apparent, during this forward movement of the ratchet the other locking pawl merely rides over the ratchet until the next notch is reached, into which it drops and thus the ratchet is againlocked against movement in either direction. The construction described provides a bottle feed such that there is no liability of any movement of the bottle during the filling and capping operations.

The bottles dhus successively fed to position beneath the filling and capping head are, in the present embodiment, raised to the head by two movements, so that the bottle takes one position for filling and is further raised for the capping operation. As hereinafter described, the capping plunger is arranged to allow' a bottle to enter the throat a given distance and the elevating mechanism is such that it may yield, or compensate in pro-portion to the height of the bottle presented. As here shown, beneath the filling head, the stationary table 155 is cut laway to receive a bottlewelevat'ing table 180 havin :a seating ad 181, the topl of this table ing norm-a y flush with the stationary table so as to receive the bottle advanced by the feed dial.' Sliding in the bracket 156 is a sleeve or casing 182 to which is secured a collar 183 (Fig. 19). Partly enclosed by this sleeve is a sprin 184 which bears at the top against the lshou der of a. tubular guide member 179 which engages the bottle elevating table 180. At the bottom the spring bears against a shouldered bushing186 which is en aged below by a nut 185 threaded into and orming part of the sleeve 182. Threaded into the tubular member 179 is a nut 187 connected with the elevating table by a rod 188. The collar 183 is engaged by the yoked end of a. lifting lever 189 pivoted as at 190, and having a cam roller 191 which rides on the bottle elevating cam 142. As the rotates, the movement of the lifting lever elevates the casing 182. As long as the pressure of the spring 184 exceeds the pressure encountered by the bottle, the elevating device moves as a unit, the table 180 being lifted by the engagement of the nut 185 against the bushing 186 and the force of the spring. As soon, however, as the pressure on the bottle reaches the predetermined point the bottle table yields or in other Words ceases its upward movement and the spring compresses to permit the further upward movement of the casing to theend of the lifting lever stroke. The cam 142 is designed to raise the bottle elevating table as soon as a bottle has been received thereon, first by a movement which lifts the bottle to filling position and,

after apause for filling, by a further stroke to lift it to capping position. For a given cam this combined stroke is always fixed. Minor variations in bot-tle heights are taken care of by t'he compensating mechanism described and the apparatus is adapted for bottles of different standard sizes by raising or lowering the head as described.

Since the bottles are being filled with liquid under pressure, means is provided for sealing the bottles in the filling head. Although capable of vario-us constructions, as here shown, carried by the filling head is a compressible gasket 204 bearing at the top against an abutment ring 205 hereinafter referred to, and engaged about the bottom edge by an angle ring 206 carried by a slotted yoke 207 riding on the pins 208 which are carried by the head. This yoke is moved against the sealing gasket to contract the same by means of oscillating arms 209 carrying adjustable pins 210 arranged to engage lugs 211 on the yoke 207. The arms 209 are connected by a pivotal shaft 2112 and one of them is provided with an extension 213 to which is secured a rod 214 reciprocated by a l plunger 215. This plunger is connected by A a cro shaft 218 and having a cam roller 219 riding on a cam 220. This cam is keyed to a shaft 201 journaled in bearings 202. carried by the housing 129 and rotated as later described. Rotation of the cam 220 causes the arms 209 to'alternately move the compressing yoke to contract and release the sealing gasket.

In the embodiment of the invention illustrated both water and syrup are conveyed to the bottle by a nozzle connected with the twov sources of supply, this nozzle being introduced into the bottlev for the filling operation. The nozzle illustrated in Fig. 8 comprises a tube 225 sliding in a capping plunger 224, later referred to. This tube 1s provided, near its upper end, with inlet ports 226 and at the bottom with discharge ports 223 arranged to discharge the liqu1d into the bottle with a minimum amount of disturbance. To lower and raise the nozzle to and from the bottles the tube 225 is secured to a reciprocating rod 227 connected by a cross piece 228 with a plunger 229, operated, for example, by mechanism similar to that which o erates the gasket controlling plunger. Es shown, t e plunger 229 is connected by a link 316 with a rocker lever 317 pivoted on the cross shaft 218. The rocker lever 317 carries a cam roller 319 which rides on a cam 320 driven by the cam shaft 201 by being secured to a clutch member later referred to. Rotation of the cam 320 causes the nozzle to be alternately lowered into and raised from the bottle presented. f

The rocker levers 217 and 319 are held to their lduty by spring pressed rods 321 which yield 1n case the nozzle, on its downward stroke should chance to encounter a bottle already capped, or other obstruction opposing its full stroke.

There is provided means for establishing in the bottles to be filled, a counter pressure during at least a portion of the filling operation. This counter pressure may conven` iently be substantially equal to the pressure of the carbonated liquid with which thebottle is to be filled. To this end, there is provided, as an example, containermeans for carbonated liquid andfor pressure fluid, and connections between the container-means and the bottle. While this may be accomplished in various ways, in structures embodying the invention to what is now considered the best advantage, there is provided a pressure line including a reservoir for carbonated water and free gas, and the bottle is made a part of this pressure line. The air displaced from the bottles filled, discharges into the pressure line, and to maintain a balance of pressure, the gaseous contents, i. e., air and free gas, are vented upon accumulation beyond a given point. Although capable of various constructions, in that here illustrated as an example, carbonated w'ater and free gas are delivered as hereinafter described by a vpipe 10 to a reservoir formed by a container o r tank 1.1. This reservoir-.has a. water delivery pipe 12 leading from =the bottom thereof, and from the upper portion thereof 1s a counter, pressure connection with the bottle, comprlsin a pipe 13, valve chest 14 and duct 1,5, the ast opening into the fillin head. Thls connection is normall Vclose by asprlng ressed valve 16 in t e valve chest 14. A er a bottle has been sealed 1n the head, the valve is opened asv later described, and the bottle is thus made part of the pressure line.

In the reservoir 11 is a float 9 pivoted as at 17 and carrying a spindle 18 on which is a vent valve 19 seating in a vent port 20 formed in the top of the reservoir tank. Valve 16 being closed, the water and -free gas enter the reservoir and the water raises the float until the ventavalve closes. Thereafter the fiow continues until the pressure of the gas inthe line substantially equals the pressure of the carbonated water. When water is withdrawn from the reservoir as hereinafter described, and delivered to the bottles presented for filling, the displaced air from the bottles dischar es into the counter pressure connection an a new supply of Water and 'free gas fiows into the reservoir until the ressure of the free gas and air balances t e water pressure and ain -stops the How. vShould the pressure o the gaseous matter (i. e., air and free gas) reach a given point, the water level recedes suiciently to lower the float and open the vent valve. This vents the' excess gas and air and the inowing water raises the float to close the valve again. Thus the accumulated air is positively vented upon exceeding a given amount and the balance of pressure is maintained in the pressure line without permitting the relative proportion of water to drop below a given minimum.

There is provided means whereby the pressure line is supplied with free gas and with carbonated water at a minimum pressure for a given degree of carbonation. As here shown as an example, water from any suitable source flows by pipe 2 to a carbonator 3, which may be of any suitable construction. The carbonator receives gas from a drum 4 through control valve 5 and pipe 6. From the carbonator a pipe for the carbonated water leads to a reducer valve 8 from which the delirvery pipe 10 leads to the reservoir. The ordinary carbonator is not 100% efficient and consequently the carbonated product holds an excess of gas. The reducer valve 8 is set to remove substantially all of the excess gas. From the valve the water and freed gas pass to the reservoir. Thus the water supplied for delivery to the bottles has a minimum pressure for the degree of carbonation and the removed gas 1s utilized in building up the counter pressure in the pressure lime.

There is provided means for forciner the carbonated hquid into the bottles to be lled,A

and provision is further made for doing so with a given effective force. This may be accomplished for example, by an impeller working in a cylinder or the like. In the embodiment here shown, an impeller or pump is provided comprising a piston 2l reciprocating in a chamber or cylinder 22, and secured to a piston rod 23 sliding in a stufn box 24. This pum is connected with 51e reservoir and the lbottle so as to draw water from the reservoir on its suction stroke and to force the water into the bottles on the impelling stroke. To this end, as here shown as an example, a nozzle 25 (Fig. 8) connected with the reservoir in any suitable manner as by pipe 12, opens into a-passage 27 formed near the top of the cylinder. This passage is connected by a pi e 28 with achamber 29 formed near the bottom of the cylinder and communitcating therewith. In the chamber 29 is a spring pressed check valve 30 arranged to open on the suction stroke and to be closed on the im elling stroke of the piston. The passage 27) also communicates with .the cylinder 22, water being admit-ted above the piston to partially balance the pressure thereon during the impelling stroke. The connection from the pump cylirnder to the bottle is later described.

Means is provided for reciprocating the piston with a given stroke. Although capable of various constructions, as here shown, the piston rod 23 is connected by a link 31 with a rocker lever 32. This latter member carries a cam roller 33 which rides on a cam 34, driven by the upper cam shaft 201. Rotation of the cam oscillates the rocker lever to reciprocate the piston rod. In order that the lever may have a. vertical movement it is provided with a second roller 35 riding in a bracket 36.

There is provided means whereby the piston stroke is given a varying speed which is slower at the end of the stroke than at the start. With the piston operating means just described, this speed variation is controlled by the cam design. In the present embodiment the cam 34 is so laid out that the piston is given a relatively rapid movement at the start, the speed gradually diminishing. With such a construction, the flow of water into the bottle is rapid at first when there is room for splashing, but slows up as the bottle fills so that the loss of liquid by splashing is greatly reduced without loss of time in filling.

With the construction described, the amount of liquid delivered by the pump is a function of the length of stroke of the iston and uniform charges are delive to successive bottles regardless of the speed of operation or varilation in the size ofthe bottles. Apparatus embodying the invention in its entirety, however, is adapted to lill bottles of diierent sizes, as, for example, quarts, pint-s and splits. To vary the uniform charges delivered, therefore, means is provided for adjusting the stroke of the piston to suit the size of bottles beilng filled, or 1n other words, to vary-the quantity delivered as may be desirable. As here shown, the pump piston has a neutral or zero position midway of the cylinder and its stroke either way therefrom is varied by varying the etective stroke of the operating mechanism. When operating means such as that described is utilized, means may be provided for shifting the pivot on which the lever rocks. Thls varies the stroke of the driving end of the lever without affecting the stroke of the cam driven end. In the present embodiment, the lever rocks on a pivoted pin 37 carried by a block 38 which is slidable 1n a slot 39 formed in the rocker lever. This block is carried by a yoke 40 which has a sliding support on a dove-tailed bracket 41. Through the yoke 40 is threaded an adjusting rod 42` which may be rotated lin any suitable manner. tion of the rod 42 will move the yoke along the bracket 41 thus shifting the pivot 37 on which the ,rocker lever swings.

Means is provided for indicating the adjustment for which the pump is set. Although capable of various constructions, as here shown, the yoke 40 carries a pin 43 which moves in a spiral groove on a rod 44 so as to rotate the same as the yoke moves. At the end of this rod 44 is a pointer 45 revolving over a dial 46 divided to show the adjustment in terms of ounces.

As before mentioned, the apparatus illustrated is of the type which delivers a quantity of syrup to the bottle. Means is provided for delivering syrup to the bottles in 'variable measured quantlties in the same manner the water is delivered. In the apparatus shown this is accomplished by means similar to the water delivery means. The syrup impelling means comprises a cylinder 47 in which reciprocates a piston 48 on a piston rod 49. Opening out of the lower end of the cylinder is a passage 50 connecting through a check valve 51 with a nozzle 52 which is connectedby pipe 53 with a source of supply 54. The piston 48 `is reciprocated from a neutral position midway of the cylinder by mechanism which is a counterpart of the operating mechanism for the water pump. That is to say, the piston rod isl linked to a rocker lever 55 carrying a cam It will be seen that rotaa roller 58 riding on a guiding bracket 59.

roller 56 riding on a cam 57 driven by the upper cam sha t 201. The lever also carries pump and no further description is necessary.

There is provided means whereby a major portion of the water is delivered prior to the delivery of the syrup and afterthe syrup the remainder of the water is delivered. In the form of apparatus here shown this isaecomplished by the cam design. The water and syrup cams are so laid out that after the water pump has made the major part of its stroke, a pause occurs while the syrup pum operates and then the water pump continus to the end of its stroke. `By thus delivering syrup into the water, there is a reduction in foaming and the second and relatively small water charge serves Lo wa sh out any syrup in the passageway and nozzle. The cams are so arranged that the stream is unbroken during the changes of iow.

Provision is made for controlling the flow of liquid from the pumps to the nozzle. This may be accomplished for example, by

having normally closed liquid connections and positively operated means for opening said connections at the proper time. In the embodiment here shown a common passage for water and s rup leads to the nozzle and the ow therethrough is controlled by a valve spring-pressed to be normally closed. To this end, the nozzle ports 226 are ar-l ranged to register, vwhen the nozzle is in filling p'osition,'with a chamber 61 formed in the plunger 224. This chamber is-in communication with a common delivery duct 62 leading from a valve chest 63. Water is received into the valve chest by way of a duct 64 leading from the bottom of the water pump cylinder 22, and syrup by way of a duct 65 leading from the bottom of the syrup pump cylinder 47. In .the valve chest, to control the iiow to the nozzle, is a .liquidv control valve 66 secured to a valve rod 67, normallyheld closed by a sprino 68.

Means is provided for operating the valve rod to open the valve and in constructions embodying the invention to the best advantage, this operation is dependent on the position of the nozzle. That is to say, provision is made for causing the valve to open to permit the flow of liquid when the nozzle has reached the proper position in the bottle.l Means is also provided for operating the gas controlling valve 16 so as to open the latter slightly in advance of the liquid control valve,and these two operations may be performed by the same means. As shown, forv example, the valve 16 is actuated by a valve rod 69. This valve rod and the valve rod 67 are moved by an operating bar 70. This bar is secured to valve-rod v69 and is slid-able on valve rod' 67. On the latter, in a .position to be engaged by the bar, isacollar 71 adustably secured in place by aset screw 72.

t will be seen that movement-,3' of the barcauses movement of the valve rod 69 andV 229 as the latter makes its downward stroke.-

Thus, as the nozzle takes filling position, the

:valves are opened, the gas control valve loev ing opened sufficiently in advance to allow the bottle to attain its proper couuterpres' sure prior to the admission' vof the liquid. Further, the operation is such that the valves are positively controlled, theirp ening taking place only after the nozzle" as reached filling position in the bottle. y Thus there can be no premature ow of gas or liquid. To

perfect the timing as may be desirable, the pin 73 is made adjustable by being threaded through the bar 70. It is locked in position by alock nut 74. The relative opening of the two valves may be timed by shifting the collar 71. i 'l p Since one pump is making 4a suction stroke while the. other is making its impell'ing stroke, check valves are provided for the water and syrup connections. As shown, in the valve chest 63 is a s ring pressed check valve 75 for controlling t e water passage to the valve chest and a similar'valvc 76 for controlling the syrup passage. A

Thesevalves are arran ed to be closed by their springs on the suction stroke of their respective pumps and opened by the force of the impelling stroke. n

Means is provided for locking the liquid and gas control valves open. With the valve operating means just described it will be apparent that the valve rods are held 'down as long as the nozzle plunger 229 remains in engagement with the bar 70. In

order that the valves may remain open after the nozzle starts to withdraw/and while it yet remains in thevbottle, means is further -ing position by a spring-pressed dog 79.

When the cross piece reaches the lowermost position, the locking arm is caused to swing in so that its end engages the bar 70. Thus,

afterv the plunger 229 starts to rise, the bar 4 is still held down and theA valves remain' open.

- ranged to be engaged by a wiper pin 81 carried by the cross piece 228 on the nozzle plunger. As the latter rises towithdraw the nozzle, the pin 81 engages the .cam 80 and swings the looking arm out of locking position, thus freeing the bar 70 and allowing the valves to close by virtue of their springs. This release is arranged to take place as the nozzle is about to leave the bottle.

It sometimes happens that the nozzle can'- not make its full stroke, as for example,

when a crowned bottle is presented. Since' this would result in the pump pistons making their impelling stroke with the valve 66 closed, provision is made for relie-ving the excess pressure in the pumps by discharging the charge of liquid in front of the pistons. Although capable of various constructions, in that illustrated in Fig. 8, the bottom of the chamber 29 is in the form of a cylindrical nut 82 having discharge ports 83. These ports are normally closed by a spring pressed relief valve 84 slidable in a sleeve-like cap 85 which is threadedinto nut 82. This valve is arranged to open in oase the pressure in the pump cylinder increases beyond a predetermined point due, for example, to the pump operating with the passage to the head closed. A similar relief valve 86 is provided for the syrup pump.

Figs. 25 and'26 illustrate a modification arranged to give the necessary relief without loss of liquid. The piston 87 is analogous to piston 21 but it is provided with a chamber 88 opening toward the bottom or discharge end of the cylinder. This passage is formed as shown to provide a seat for a relief valve 89 sli-ding in sleeve-like nut 90, threaded into the piston, and normally held closed by a spring 91. Leading from chamber 8,8, at a point above the valve seat, is an oblique duct 92 opening into the pump cylinder behind the piston. With this construction, should the pump operate with the valve l66 closed, the excess pressure opensthe relief valve and the liquid in front of the piston Hows through the piston to the other portion of the cylinder to be drawn on again.

Since the bottles contain liquid yunder pressure they are capped while sealed in the lilling chamber. The apparatus illustrated is designed to cap the bottles with closures of the Acrown cork type. Crowns are supplied from a hopper 240 carried by the housing 129` to a-delivery chute 241. Associated with the hopper is a crown selecting dial 242 of any suitable construction to select"the crowns and deliver them, properly faced, Ylo

the chute. j y

The dial is rotated b means of a hopper shaft 243 driven by a gevel gear 244 meshing with a similar gear 245I on a cross shaft 246. This latter carries a spur gear 247 meshing with a pinion 248 ona shaft 249-,-

which also carries a sprocket 250. The sprocket is driven by a chain 251 which, in turn, 1s driven by a sprocket 252 on the upper cam shaft 201.

leans is provided for intermittently stopping the flow of crowns so as to deliver one crown at a time, at the same time permit- 'ting the delivered crown to have the benefit of the gravity force of the succeeding column of crowns. As here shown, as an example, the lower end of the' chute is provided with a slot in which operates an escapement lever 253, pivoted as at 256 and` having two crown-engaging projections 257, 258 spaced apart somewhat more'than the width of a crown. l v

Fig. 15 illustrates the position of the apparatus during filling. There is a crown crown, and the next or second crown is held back by the ment lever. The latter member is oscillated by means hereinafter described, and upon its movement tothe position of Fig. 14, the second crown is released. For a brief interval the entire column of crowns is free to move so that this released \crown receives sulicient push to cause it to slide i-nto the head. Meanwhile the lever movement elevates projection 257 to engage the skirt of the next or third crown in the manner shown in Fig. 14. The reverse lmovement of the escapement lever permits this third projection 258 of the escapevin the head which may be termed the first crown to drop into the former position of the ing. In the head, in the present embodiment tlhe` crown is stopped by projections 1 on the abutment ring 205 in s uch position (Fig. 16)

as not to interfere with the filling operation.

Since liquid under pressure is involved, there is provided means for sealing the crown entrance opening during the filling operation, and this sealing means may comprise a gasket pressed against the head by a predetermined force. As here shown, as an example, sliding in a tubular-bracket 260 is a sleeve 261 carrying an annular rubber gasket 262 of a size to surround the crown entrance opening. In telescopic relation with this sleeve is a second sleeve 263 also sliding in bracket 260. Compressed between the two shouldered end portions of the two sleeves, as appears in Fig. 14, is a spring
